13. Observadores inteligentes de estado : propostas / Intelligent state observers : proposals
The state observer problem arises from the necessity of controlling plants whose state can not be measured. Usually dynamic model based observers are used to solve this problem, for estimating unknown state. In this thesis an alternative solution for this problem is presented. Various proposals for intelligent observers are made based on mappings between sub

14. BILINGUALITY MEASUREMENT: A PROPOSE / MEDIDAS DE BILINGUALIDADE: UMA PROPOSTA
This study proposes a methodology to evaluate degrees of bilinguality. The objective is to quantify the concept bilinguality. Considering that the bilingual behavior should not be taken as one`s universalist or essentialist aspect, objective knowledge of statistics and probability, and formal methodology of data gathering, for example, do not cope with the s

15. A comunicação suplementar e/ou alternativa na vida de pessoas com paralisia cerebral, adultas e institucionalizadas
The aim of this work, was to verify how the AAC can affect the life of two adults with a non articulated speech, due to the cerebral palsy, on both, considering the fact that they are living as internals in an Institution. It was chosen as method the case study with observation evolved by a six months period of time. It has been made reports and pictures (mo

16. Study of speed estimation of induction motor without state observer and Kalman filter / Estudo de estimadores de velocidade de motor de indução com observadores de estado e filtro de Kalman
This works presents through of the simulation a comparative study of the sensorless of speed estimation of induction three-phase motor using state observer and Kalman filter. A comparative analysis of the performance of the deterministic and stochastic estimation strategies using adaptive observers and estimators based on extended Kalman filter was realized.

17. Variação diária e anual de freqüência e atividade do Boto Cinza Sotalia guianensis em Pipa, Nordeste do Brasil
The aim of this study was to investigate the daily and annual variation in frequency and in activity of an estuarine dolphin population, Sotalia guianensis, in Brazilian northeastern. Thus we estimated the daily variation and seasonality in frequency of adult and immature and in behavior of socialization, aerial activity, foraging of a boto equatorial popula

18. Ensino de discriminações condicionais por imitação: efeitos de dois arranjos de apresentação de tentativas.
Imitation can be defined, in general terms, as the similarity of behavior between two organisms when the response topography of one, the imitator, is similar to nd controlled by the behavior of the other, the demonstrator. Along the years there has been a lot of controversies involving imitation`s conceptualizations and discussions on how it is produced and

19. Comportamento das curvas resultantes da interação das leituras visuais e digitais na triagem de auto-anticorpos (FAN) pela imunofluorescência indireta
The indirect immunofluorescence test is widely used in the clinical pathology laboratory. Among the tests in this group we have FAN, which means research of antibodies against components of the nucleus, nucleolus, cytoplasm and mitotic spindle. This test, used in the selection of auto antibodies, imposes some difficulties for its application such as: it requ

20. IDENTIFICACIÓN DE SISTEMAS DE EXTRUCTURAS MECÁNICAS Y APLICACIONES / IDENTIFICATION OF MECHANICAL SYSTEMS WITH APPLICATIONS / IDENTIFICAÇÃO DE SISTEMAS DE ESTRUTURAS MECÂNICAS E APLICAÇÕES
The aims of this work are three: First, to make a brief review of linear system and estimation theory used in mechanical structure problems. Second, to study an algorithm called ERA (Eigensystem Realization Algorithm) that provides a minimal realization using the input (forces, moments, impulses) and output signals (accelerations). Third, to develop some num

21. \"Estudo dos Processos de Aprendizagem Individual e Social em Macacos-Prego (Cebus Apella) a partir de Manipulação de uma Caixa-Problema\". / Study of individual and social learning processes in Tufted capuchin monkeys (Cebus apella) through the manipulation of a problem-box
Capuchin monkeys (Cebus apella) are excellent object handlers. This work aimed to study individual and social learning processes which took place during the aquisition of a task that consisted on opening bolts from a problem-box. Two groups were used and, from each group, one subject was trained to perform the task. The analysis of the individual learning pr

22. Brincando no ambiente natural : uma contribuição para o desenvolvimento sensorio-motor da criança portadora de paralisia cerebral
The objective of this paper was to build a playing dynamics for a child with cerebral palsy, together with his mother in a natural environment. Games, naturally, develop the motor-sensory. Since playing is part ofthe human being growth, we perceive it is very easy to be assimilated and becomes a strong stimulation source, through creativity, for that child.

23. Dieta, padrão de atividades e area de vida de um grupo de bugios (Alouatta fusca) na reserva de Santa Genebra, Campinas, SP
The behavior and ecology of a group of six brown howlers were studied weekly during 12 months in the Santa Genebra Reserve (22º49 45"S and 47º06 33"W), near the city of Campinas. The reserve has 250 ha of secondary, mesophitic, semi-deciduous forest. Simultaneously, the phenology of 186 trees of 72 species and 29 families was monitored. The "scan sampling

24. Analise da comunicação sonora no anu-branco guira quira (aves: cuculidae), avaliações eco-etologicas e evolutivas
The vocal repertoire of the Guira Cuckoo Guira guira is described together with its behavioral contexts. The natural groups of Guiras that live at the Campus of the Universidade Estadual de Londrina in Paraná, Brazil, were studied. Important observations and recordings were also obtained from birds raised in captivity in the middle of the town and in the su
